How OS X “Mavericks” works its power-saving magic

Apple execs talk up the new features in OS X Mavericks. At yesterday’s Worldwide Developer Conference (WWDC) keynote, Apple made some bold claims about the future of battery life in its laptops. A new 13-inch Macbook Air, for instance, should now run a full 12 hours on a single charge , up from 7 in the previous model. Assuming that testing bears out Apple’s numbers, how did the company do it? The obvious part of the answer is “Haswell”—but that turns out to be only part of the story. The power efficiency gains found in Intel’s new Haswell CPUs should provide modest gains in battery life, and such gains were widely expected. Back in January, Intel claimed that the new Haswell CPUs featured the “largest generation-to-generation battery life increase in the history of Intel” and said that the chips were the first of its architectures designed “from the ground up” for Ultrabooks and tablets. The new chips run at lower clockspeeds and at lower wattages. Less expected was the announcement of OS X 10.9 “Mavericks” and its own focus on mobile power usage. While Apple made a few comments during the keynote about the new technologies meant to enable longer battery life, more information appeared later in the day with the separate release of a Core Technology Overview (PDF) document that offers a high-level look at some of the Mavericks internals.

New OS X uses Windows file sharing by default

@darth News about the new release of OS X, ” Mavericks ,” is trickling out as developers and other WWDC attendees post information about it to the Internet. However, hidden a bit down in Apple’s OS X Mavericks Technology Overview document is an interesting tidbit: SMB2 is replacing AFP as the default file sharing protocol for OS X. AFP— Apple Filing Protocol —has a long pedigree that stretches all the way back to the Mac’s early days (and even a bit before that). Contemporary AFP piggybacks on top of TCP/IP for transport, but it supports a few Mac-specific things that other network file protocols don’t, like type and creator codes. These don’t matter as much as they used to, but OS X’s HFS+ file system supports a pretty rich amount of metadata, and AFP transports and preserves that metadata. But AFP isn’t particularly friendly to non-Apple systems, and no operating systems other than OS X support it natively. This wouldn’t be such a big deal, except that one of OS X’s killer features, Time Machine, only works over a LAN with destinations that support AFP. This is at least in part because of Time Machine’s reliance on Unix hard links, and also in part because it has to be able to ensure that any OS X files with HFS+ specific metadata are correctly preserved. This in turn means that third-party Time Capsule devices have to rely on reverse-engineered implementations of AFP to continue functioning, and OS X updates occasionally break third-party Time Capsule devices, sometimes for weeks.

AMD wins race to 5GHz CPU clock speed, in which it was the sole participant

AMD has refreshed its lineup of eight-core FX chips in what sounds like some straightforward overclocking of last year’s products. The FX-9590 claims a clock speed of 5GHz in turbo mode, making it the “world’s first commercially available 5GHz CPU processor,” while the FX-9370 lags slightly behind at 4.7GHz, as compared to the 4.2GHz top speed of the current FX-8350 . Both new CPUs are based on the familiar Piledriver core, which has a reputation for being relatively cheap and easily overclockable (honestly, the 5GHz barrier was obliterated long ago ), but far behind an Intel Core i5 in terms of all-around computing. This is especially true since the launch of Haswell , which largely avoided clock speed increases in favor of architectural tweaks that didn’t compromise efficiency . Maingear plans to pick up the 5GHz part for use in a gaming system coming this summer, but there’s no word yet on pricing or even general availability for DIY upgraders. Now, we’re just speculating, but with AMD increasingly focused on APUs, it’s possible that today’s chips will represent the FX’s lap of glory. Filed under: Desktops , Gaming , AMD Comments

Quantic Dream’s The Dark Sorcerer demo highlights PS4’s graphics power

Remember the Emotion Engine from back in the PS2 days? Well, Sony’s still on about the emotional connection its consoles will bring to gamers — specifically, that of the PS4 . And to showcase the console’s graphical sophistication, Worldwide Studios head Shuhei Yoshida played a 12-minute tech demo of Quantic Dream’s upcoming PS4 title, The Dark Sorcerer . The majority of the demo focused closely on the sorcerer in question, giving gamers an early glimpse of the nuance and hyper realistic expression capable in characters’ eyes and faces. Only a short snippet was shown on stage here at E3, but if you want to digest the entire thing, Sony’s planning to unveil the full 12-minute demo tomorrow afternoon.

iOS 7 Adds Multitasking for All Apps

Until now, multitasking in iOS has been fairly limited. Now, it’s going to work for all apps—and Apple says it’s going to provide background updates to all apps—and Apple says all those background cycles aren’t going to hurt your battery life. Read more…

Apple announces flatter, sleeker iOS 7

A new version of Apple’s mobile operating system, iOS 7, was announced at the company’s Worldwide Developer Conference (WWDC) at the Moscone Center in San Francisco. The release will feature, among a number of changes, a departure from the bubbly, skeuomorphic design that has prevailed on both iOS and OS X for the last several years in favor of flatter, more angular design elements influenced by Apple SVP of Industrial Design Jony Ive. The most front-facing part of the OS, the home screen, now has app icons that lack the dimension and gloss effect of previous versions. Design elements within the icon, like the musical note on the Music app icon, appear as a flat design flush with the background rather than a cutout like before. iOS 7 isn’t doing away completely with dimensionality, as some text elements shown in the intro video still feature embossing, and Ive emphasized that the OS focuses on “depth and vitality.” The look of several key apps in iOS 7. Many of the skeuomorphic touches are also gone from the OS, such as the textured paper in the iBooks app and the leather-bound elements in the Calendar app. Of the Game Center redesign, Apple SVP of Software Engineering Craig Federighi stated, “we just ran out of green felt.” Read 14 remaining paragraphs | Comments
